Panitumumab (Vectibix®) in Cutaneous Squamous Cell Carcinoma (SCC) (PASCE)

An Open Label Multicentric Phase II Study of Panitumumab (Vectibix®) in Cutaneous Squamous Cell Carcinoma (SCC)

Squamous Cell Carcinoma (SCC) is one of the most common malignancies in caucasian population. The effect of the immune system on the development of skin tumors has been demonstrated in transplant patients taking immunosuppressive agents (65 fold risk increase). It has been reported that activation of EGFR and RAS signaling pathways play an important role in disease progression maybe through downregulation of the immune system.

The investigators want to treat unresectable SCC patients with an antibody against EGFR (Vectibix®, panitumumab). This antibody induces tumor regression in metastatic colorectal cancer and has been approved as single agent for this indication.

The investigators want to measure the response rate but also analyze the modification of expression profile of some key proteins involved or supposed to be involved in the signaling pathways of EGFR and in the regulation of the immune system. Chemokines such as CCL27 have been shown to play a critical role in the skin-associated immune response by regulating T cell homing. Pivarcsi et al have reported that downregulation of CCL27 is mediated by activation of EGFR/RAS/MAPK signaling pathways.

詳細な説明

This is an open-label, multicentric study of 17 patients with skin squamous cancer cell.

Eligible patients should not be suitable for immediate surgery. If they have only one tumor, it should be greater than 3 cm2 in order to allow multiple biopsies.

Patients will receive six infusions of Panitumumab 6 mg/kg every 2 weeks or until progression if earlier.

Patients will be assessed at baseline, at week 6 and then every 12 weeks till progression. In addition to clinical examination, evaluation tools will include photography and CT-scan, MRI or PET-scan.

Skin and tumor biopsies will be performed during first cycle at baseline and at days 2, 4, 8, 43, 85. Blood collections for translational research will be done during first cycle at baseline and at days 2, 4, 8,15, 43, 85. Blood collection for hematology and chemistry assessment will be done each 4weeks.

Patients presenting with a stable disease or a tumor response at week 12 will be eligible for maintenance cycles consisting in an infusion of panitumumab every 2 weeks till progression.

主要な結果の測定

結果測定
メジャーの説明
時間枠
Overall Response Rate (ORR)
時間枠:via imaging every 12 weeks
To measure the efficacy of Panitumumab for SCC in terms of Overall Response Rate (ORR). Overall Response Rate (ORR) is defined as the sum of complete and partial tumour responses seen, divided by the total number of evaluable patients.
via imaging every 12 weeks

二次結果の測定

結果測定
メジャーの説明
時間枠
To assess the safety profile of panitumumab in SCC
時間枠:at each visit
Proportion of all adverse events will be reported. CTC scale 3.0 will be used with the exception of skin- or nail-related toxicities, which must be graded using CTC version 3.0 with modifications (Appendix E). Patients will be followed for safety until closure of study.
at each visit
Time to treatment failure (TTF)and Time to treatment progression TTP
時間枠:via imaging, every 12 weeks
Time to treatment failure (TTF) is defined as the time from date of first dose of study medication to first occurrence of any following event : documentation of objective tumor progression, toxicities requiring prematurely stop of treatment or death. TTF will be calculated according to the Kaplan-Meier technique. Time to Progression will also be calculated. Subjects without evidence of progression at the end of follow up will be considered as censored.
via imaging, every 12 weeks
To measure the duration of response.
時間枠:via imaging, every 12 weeks
Duration of overall response will be measured according RECIST guidelines version 1.1 Duration of response is measured from the time measurement criteria are first met for CR/PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded on study).
via imaging, every 12 weeks
To explore the gene expression profiles in SCC under panitumumab treatment (i.e CCL27, EGFR,…).
時間枠:Skin and tumor biopsies will be performed at baseline and at days 2, 4, 8, 43, 85. Blood will be collected at baseline and at days 2, 4, 8, 43, 85
Results will be presented as proportion of each expression type.
Skin and tumor biopsies will be performed at baseline and at days 2, 4, 8, 43, 85. Blood will be collected at baseline and at days 2, 4, 8, 43, 85
